A commercial epoxy floor is a full system, not just a coating, slab prep, primer, body coat, aggregate, and topcoat matched to the load. Oshawa Concrete installs epoxy systems for warehouses, service garages, and manufacturing spaces, sized to the chemical and traffic demands and warranted as a system. Every project starts with a free written estimate.
Commercial epoxy fails for one reason 90% of the time: the slab underneath was not prepped to spec. A coat applied over a contaminated, uneven or moisture-laden slab will lift, blister or peel inside a year regardless of how good the epoxy itself is. The slab is the work; the epoxy is the finish.
We diamond-grind the slab to the manufacturer's prep profile, test moisture and remediate where needed, fill cracks and joints with a compatible filler, then install the matched primer, body coat and topcoat in the right sequence with the right cure between coats. Aggregate is broadcast where slip resistance matters.
We start with the use case, chemical exposure, traffic loads, wash-down frequency, slip needs, and specify the matched epoxy system, primer, body, aggregate and topcoat, that meets all of it.
Diamond-grind the slab
The existing slab is diamond-ground to the system's prep profile, contaminants and old coatings are removed, and the surface is left clean, profiled and ready for the primer.
Prime and body-coat
Primer is applied across the prepped slab to bond with the concrete, the body coat goes on next at the right thickness for the system, and aggregate is broadcast where slip resistance is specified.
Topcoat and return to service
The topcoat is applied to seal the system and provide the wear surface, the floor cures to the manufacturer's schedule, and the space is handed back ready for traffic at the right interval.
Beyond the install
Specifying the Right System Saves Years
Commercial epoxy systems vary hugely by chemical resistance, abrasion class, temperature tolerance and slip rating. The wrong system in a kitchen wash-down area or a service-bay floor will fail in months even if the install is flawless. We specify based on the real use, not the cheapest option that fits the budget.
Where the install is part of a larger fit-out, we coordinate with adjacent polished concrete in office areas and loading-dock work outside the building so the floor systems hand off cleanly.
Slab prep, chemical resistance, slip ratings and what makes commercial epoxy worth specifying.
A properly specified and installed system lasts the better part of a decade or longer in most commercial environments. Wear comes from traffic and chemicals; the system spec determines how it handles each. We size the spec to your use.
Diamond grinding to the manufacturer's prep profile is our standard, removing contaminants, old coatings and surface laitance. Where moisture testing flags a high-vapor slab, a moisture-mitigation primer goes on first. Skipping prep is why coatings fail.
Yes, with the right system spec. Wash-down floors get a system with chemical resistance and slip aggregate; food processing gets a system rated to that environment; service garages get a system rated for hot tires and automotive fluids. The system matches the use.
Foot traffic typically a day after the topcoat; full vehicle or chemical service later in the cure schedule. We give you a clear return-to-service timeline before the install so you can plan production around it.
Sometimes, but usually we remove the failed system back to clean concrete first. Installing over a failing layer just inherits its failure mode. The honest scope often includes removal as a line item; the quote tells you up front.
Client reviews
What Oshawa Operations Say About Their Commercial Epoxy Floors
Three contractors quoted slab prep as a paint roller and a primer. Oshawa Concrete quoted diamond grinding and explained why. Two years in, floor is still tight to the slab, no peeling.

★★★★★
Service-bay system rated for hot tires and automotive fluids. Wash-down works, no spalling at the floor drains, and the slip aggregate is doing its job in winter.

Service Garage Owner, Toronto
★★★★★
They specced the system to the actual chemical exposure in our plant, not the cheapest option. Worth every dollar; the previous floor had failed in 14 months.
X. U.
Manufacturing Plant Manager, Brampton
★★★★★
Coordinated install around our shift schedule. Floor was returned to service at the timelines they quoted, no surprises, no slipped delivery dates. Real professionals.
